Abstract

METODO PER IL RECUPERO DEI REAGENTI DI BASE PER LA SINTESI DI VETRI ZBLAN DA SOLUZIONI PURIFICATE, IN CUI DUE SOLUZIONI ACQUOSE PURIFICATE VENGONO MESCOLATE FRA LORO IN OPPORTUNE CONDIZIONI DI RAPPORTI PONDERALI, DI TEMPERATURA E DI EQUILIBRI CONCORRENTI, IN MODO DA OTTENERE PER PRECIPITAZIONE UN PRODOTTO CONSISTENTE IN UN SALE DOPPIO CON BASSA SOLUBILITA', CHE VIENE IN SEGUITO SEPARATO DAL SOLVENTE, PER ESEMPIO PER FILTRAZIONE, ED UTILIZZATO PER LA PRODUZIONE DEL VETRO.METHOD FOR THE RECOVERY OF THE BASIC REAGENTS FOR THE SYNTHESIS OF ZBLAN GLASSES FROM PURIFIED SOLUTIONS, IN WHICH TWO PURIFIED WATER SOLUTIONS ARE MIXED BETWEEN THEM IN SUITABLE CONDITIONS OF PONDERAL RATIO, TEMPERATURE AND PERFORMANCE OF SUITABLE PERFORMANCES CONSISTING OF A DOUBLE ROOM WITH LOW SOLUBILITY, WHICH IS FOLLOWED SEPARATELY FROM THE SOLVENT, FOR EXAMPLE BY FILTRATION, AND USED FOR THE PRODUCTION OF GLASS.
